Select a Port — Port on which STP is enabled.
STP — Enables or disables STP on the port.
Fast Link — When selected, enables Fast Link mode for the port. If Fast Link mode is enabled for
a port, the Port State is automatically placed in the Forwarding state when the port link is up. Fast
Link mode optimizes the time it takes for the STP protocol to converge. STP convergence can take
30-60 seconds in large networks.
Port State — The current port STP state. If enabled, the port state determines what forwarding
action is taken on traffic. Possible port states are:
Disabled — The port link is currently down.
Blocking — The port is currently blocked and cannot be used to forward traffic or learn MAC
addresses. Blocking is displayed when Classic STP is enabled.
Listening — The port is currently in the listening mode. The port cannot forward traffic nor
can it learn MAC addresses.
Learning — The port is currently in the learning mode. The port cannot forward traffic
however it can learn new MAC addresses.
Forwarding — The port is currently in the forwarding mode. The port can forward traffic and
learn new MAC addresses.
Speed — Speed at which the port is operating.
Path Cost (1-200000000) — The port contribution to the root path cost. The path cost is adjusted
to a higher or lower value, and is used to forward traffic when a path being rerouted.
Default Path Cost — The default path cost of the port is automatically set by the port speed and
the default path cost method.
The default values for long path costs are:
Ethernet - 2000000
Fast Ethernet - 200000
Gigabit Ethernet - 20000
The default values for short path costs (short path costs are the default) are:
Ethernet - 100
Fast Ethernet - 19
Gigabit Ethernet - 4
